1. Manual Wafer Butterfly Valve Description

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

5.FAQ

 

1. What is manual wafer butterfly valve?

A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.

 

2. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.

 

3. What is the working principle of manual wafer butterfly valve?

 A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

 

Q: Valve category can fill the trunk door, branch valve Mody?
Valve category refers to the type of valve, the big species are divided into: butterfly valve, gate valve, globe valve, ball valve, check valve, control valve, trap and electric valve,
Q: How do you calculate the valve wall thickness, pressure, and other valve design calculations in a spreadsheet?
Which standard does the wall thickness refer to? ASME B16.34?Design and calculation depends on what standard you chooseOr have you found the standard yourself and read it yourself?You choose what standards, design parameters reference, interpolation or fitting, how to fit, are their own sayI wrote a excel series of valve calculations, it does not take long to writeFor long-term useIn order to improve efficiencyOr write your own database program is better
Q: I used to do pumps, and now feel the future of the valve better, looking for a valve to do proxy, but my own economic strength is not good, I do not know if there is no possible to do?
As the two floor said, looking for agents depends on your targeted customer base is better sign is the price of comparative advantage of the brand. Now the valve on the market in Fujian, Wenzhou. Especially, these valves are faced with the market price, the quality of course needless to say. Maybe these valves would sell large the early recovery of funds, is also rich. But for a long time, the problem appeared, quality problems will make you sleepy fishing, I suggest you. You can't do anything sales quality and good reputation of the valve.In the few I know better. Now the best reputation is Guanlong, but the price comparative advantage or spring.
Q: How to check the quality of the valve?
First, visual inspection of the valve appearance, followed by a spectrometer to check the material, material, and then look at the hydraulic test pressure, whether there is leakage.
Q: What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,
Q: What are the types of valves?
1.1 classification by purpose and functionx09 (1) cut-off valve is mainly used to cut off or switch through the media flow, including gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball plug valve, needle type instrument valve, etc.x09 (2) control valve is mainly used to regulate the flow of medium, pressure, etc., including regulating valve, throttle valve, pressure reducing valve and so onx09 (3) check valves are used to prevent backflow of media. Check valves with various structures are includedx09 (4) diverter valves are used for separation, distribution, or mixing of media, including distribution valves and traps for various structuresx09 (5) safety valves are used to protect the medium against overpressure. Various types of safety valves are included1.2 classify by main parameters
Q: What do letters represent in the QF-2 and PX-32 valve models?
Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
Q: Valve pressure grade division
Valve (Famen) is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q: Yongde jiekelong valves and valves of the good faith
Interior decoration is the most cost-effective brand, switches, sockets, Zhejiang, Yongkang, France and Germany electrical appliances. Plumbing valve, Zhejiang, Yongde, Yongkang letter. Bathroom accessories Fujian Nanan Jomoo bathroom.
Q: How are the types of valves classified?
Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion.
